Mass affects the time it takes an object to free fall when air resistance is not a factor.

• True

• False

Which would fall with greater acceleration in a vacuum—a leaf or a stone?

• the leaf
• the stone
• They would accelerate at the same rate.
• It is difficult to determine without more information.

When there is no air resistance, objects of different masses dropped from rest

• fall with equal accelerations and with equal displacements.
• fall with different accelerations and with different displacements.
• fall with equal accelerations and with different displacements.
• fall with different accelerations and with equal displacements.

Which would hit the ground first if dropped from the same height in a vacuum—a feather or a metal bolt?

• the feather
• the metal bolt
• They would hit the ground at the same time.
• They would be suspended in a vacuum.
